Armenteira Monastery

Highlight • Religious Site

Of Renaissance and Baroque style, from the 16th and 17th centuries, the magnificent Romanesque church built by its first Cistercian abbot in 1167 is also preserved. It has a Latin cross plan with three naves and three apses. The cover is perhaps the most remarkable of the temple, with its six archivolts supported on as many pairs of columns and above, a beautiful openwork rose window.

One of the jewels of this island is the Ermita da Toxa, from the 12th century, popularly known as the Chapel of the Shells and which worships the Virgen del Carmen, patron saint of sailors. The chapel was modified in the 19th century, being restored, enlarged and completely covered with thousands of scallop shells, since it is a good insulator from the sea humidity.

Chapel of the Shells of A Toxa

Highlight • Religious Site

Why is the Church covered in scallop shells? You should not leave without knowing that you have on your right the only chapel in the world covered with scallop shells. Originally when it was built in 1909 it was not. His story is the result of chance.

The façade where the altar is, is oriented to the South and the rains continually hit its walls, producing humidity and deteriorating the structure. At the end of the 40s of the 20th century, Raimundo Riestra Calderón, II Marqués de Riestra, summoned a bricklayer from the town of O Grove, named Anselmo Millán, with the intention of offering him a solution to this problem that he sees - They had been dragging for almost four decades. The man advised him that a traditional way to prevent the penetration of water was to imbricate scallop shells on the entire surface, making the water slide down all of them without wetting the interior. He thought it was a great idea and accepted the proposal. When they finished covering the façade, the Marquis liked it so much that, as manager of the Spa, he ordered the entire church to be covered with shells. It was slow work that took several years, beginning in the late 1940s and ending in the early 1950s.

And one last detail, if you were transported 120 years back in time to the same point where you are, you would not step on land but you would be floating in the water together with the Church. Almost all of this garden was an old salt mine that loses its origins in the remotest past. It was filled in at the beginning of the 20th century.

On the island there are some of the most beautiful beaches with crystalline waters in Galicia. The many white sand beaches located in the sheltered coves of the island can be enjoyed after a long day of walking. The island is home to many protected birds that spend part of the year in this part of the national park.

The famous shell church was formerly dedicated to San Sebastián, but after the reform, the Virgen del Carmen was substituted as the main image. This chapel venerates the famous San Caralampio III, a 19th-century martyr who is the patron saint of skin diseases. The patronage and veneration of this special place, the thermal waters of the thermal baths on the island of A Toxa, are used as a skin-healing therapy, so people have been going to this chapel since ancient times to ask for the protection of this saint. Why is the church covered with scallop shells? It is the only chapel in the world covered with scallop shells. Originally built in 1909, this was the result of chance. The facade, where the altar is located, faces south, and rain constantly beats down on the walls, creating dampness and damaging the structure. At the end of the 1940s, Raimundo Riestra Calderón, II Marqués de Riestra, summoned a mason to offer a solution to this problem, which had dragged on for almost four decades. The man informed him that a traditional method of preventing water infiltration was to cover scallops with scales all over their surfaces, allowing water to slide down them without wetting the interior. He thought the idea was great and accepted the proposal. When the facade was finished, the Marquis liked it so much that, as administrator of the spa, he ordered the entire church to be covered with shells. It was a slow process that took several years, beginning in the late 1940s and ending in the early 1950s. And one last detail: If you were transported back in time 120 years to the same point where you are now, you wouldn't walk on land, but would float in the water along with the church. Almost the entire garden was an old salt mine, lost in the distant past. It was filled in at the beginning of the 20th century.

Walking poles useful as downhill on the rocks, bit slippery in parts after rain. Beautiful walk.

The first Cistercian monks founded their monasteries in the valleys, so the Monastery of Armenteira is located in a beautiful valley fertilized by water, a metaphor for the grace of God poured into the hearts.
